-Re: Not able to start the NodeManager

Not sure why the the properties in the .bashrc are not being picked by the
scripts. Why is it? I am using Ubuntu 11.10. I had to export some variables
in the `libexec/hadoop-config.sh` and `conf/yarn-env.sh` to get 0.23 work
in a cluster.
Also, I had to add `yarn.resourcemanager.resource-tracker.address`,
`yarn.resourcemanager.scheduler.address` in the yarn-site.xml for the NM to
know the location of the RM.
